The Ethnobotanical Garden of about 4 hectares, was established in 1991. It is divided into 5 sections according to the 5 local ethnic groups i.e. Chinese, Iban, Bidayuh, Malay and Melanau, and Orang Ulu. The one hundred and sixty-two (162) plants on display are commonly used by the local communities for food, medicines, handicrafts, ceremonial and religious rituals, and other traditional purposes. Among the interesting plants found here are: Tongkat ali (Eurycoma longifolia) and Hujan panas (Goniothalamus velutinus) for medicinal purposes, Daun tubu (Pycnarrhena tametacta) for food flavouring, and Tepus buluh (Costus speciosus) for ceremonial rituals.
